Part of the John Deere Repair Manuals.
This is the Diagnosis and Tests technical manual (TM134219) for 2015-2021 John Deere 5085M, 5100M, 5100MH, 5100ML, 5115M and 5115ML tractors. It is the book you open when a code appears or something quits: trouble-code diagnostics for the CCU, ECU, EIC, HCU, ICC, JDLink and PTR controllers, symptom charts, circuit-by-circuit electrical schematics with matching component locations and connector pinouts, plus live tests with real target values - relief pressures, clutch leak-check limits, cooler flows, hitch cycle times. Written for the Final Tier 4, CAN bus era of the 5M line, in both PowrReverser and SyncShuttle versions. Be clear on scope: this is the find-the-fault manual, not the teardown manual. Diagnose with a gauge and a meter instead of guessing.
